Stochastic gradient methods for machine learning and optimization problems are usually analyzed assuming data points are sampled with replacement. In practice, however, sampling without replacement is very common, easier to implement in many cases, and often performs better. In this paper, we provide competitive convergence guarantees for without-replacement sampling, under various scenarios, f...

In this paper, we embed the microeconomic decisions associated with investment under uncertainty, capacity utilization, and machine replacement in a general equilibrium model based on putty-clay technology. We show that the combination of log-normally distributed idiosyncratic productivity uncertainty and Leontief utilization choice yields an aggregate production function that is easily charact...

BACKGROUND Renal replacement therapy (RRT) has been implemented extensively in people to facilitate recovery from acute renal failure (ARF). RRT has not been explored in horses, but might provide a further treatment option in horses with ARF. OBJECTIVE To investigate efficacy and safety of RRT in horses. ANIMALS Five healthy adult horses. METHODS A prospective study was performed on horse...

Vintage capital models of the economic growth theory describe optimal capital replacement under various restrictions on technological change, available resources, and natural environment. Such models are represented by non-linear Volterra integral equations with unknowns in the integration limits [1, 2]. In Operations Research and management science, similar processes of asset (machine, equipme...

today power consumption is considered to be one of the important issues. therefore, its reduction plays a considerable role in developing systems. previous studies have shown that approximately 50% of total power consumption is used in cache memories. there is a direct relationship between power consumption and replacement quantity made in cache. the less the number of replacements is, the less...

to evaluate the effect of replacing the almond meal on viscoelastic properties of rice cake, stress relaxation test was carried out. stress relaxation test were conducted using a texture analyzer machine. constants of the peleg - normand and the extended maxwell model for variables were calculated. the results showed that with increasing strain rate increased amount of k1, k2 and decay forces, ...
